Abstract
In the title compound, C(6)H(11)N(3)O(3), the imidazolidine NH group is involved in a three-center N-H⋯O hydrogen bond, with intra-molecular and inter-molecular branches, to the nitro group O atoms. The centrosymmetric dimers that are formed are further connected by O-H⋯O hydrogen bonds between the hy-droxy and nitro groups into a two-dimensional polymeric structure extending parallel to (101).Entities:

| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
